Scientific Notation

Scientific notation is useful when working with very large or very small
numbers. Scientific notation shows a small number (less than 10) times
10 raised to a power. For example, the 1984 Gross National Product of
the United States was $3,662,800,000,000. In scientific notation, this is
12
3.6628 x10 . For very small numbers the decimal point is moved to the
right and 10 is raised to a negative power. For example, 0.00000752
can be written as 7.52 x 10
When a calculation produces a result with more than 12 digits, the
number is automatically displayed in scientific notation, using a capital
in place of "x10^".
